Cross top beam Cross type metal top beam Cross type metal top beam Metal top beam model: B, B, B,, B
Metal long beam: B
Product use:

The B-type cross metal hinged roof beam can be matched with various types of friction pillars or single pillars with hinged roof covers to form a metal bracket.

The cross metal hinged roof beam can be connected to itself or to each other with the B-shaped roof beam to form a square frame network structure, which is better than the upper and lower tunnels and working face ends of the mining working face with an inclination angle greater than ℃. Support to prevent the bracket from tipping over and eliminate unsafe factors caused by uneven pressure on the top plate. Good quality and reasonable price. This type of roof beam is a hinged roof beam that can be used with various types of roof beams. The single metal pillars are combined to form a metal bracket, which is a high-strength roof beam used to support horizontal and gently inclined mining working faces in coal mines. Because this kind of roof beam can cantilever support the roof above the conveyor road in front of the coal wall of the working face, there is a large unsupported space between the coal wall and the pillars. Therefore, it provides conditions for the use of new coal mining machinery and flexible transporters to achieve general mechanization of coal mining. It is a necessary supporting equipment for high-end general mining and new high-end mining technology
